To all wlzom 65 may concern:

Be it known that 1'. WILLIAM Kroc-KB. a citizen of the United States,residing in the borough of Brooklyn, county of Kir ciity ancl State ofNew York, h we im'cntcil cerlain new and useful Improvements inAntomati-z Clutches, of which he following is aspecification.

My inveni'icn relates to clutches for autonmtically connecting orclisconneciing a machine from its driving mechanism, and while Ihareshmm it in connection with pin clutches to which it is particularlywell adapted. it me." also he found useful in (onnec-t' rilh cmlchc ofoihcr kinds.

It has for its object to provide a clutch "which will he simple. andelllcient, col-lain in operation. will not become broken while heingconnecfed or llSCUlllQClQkl, and is adapted par" nlnrly to drawingpunching and o to he c pubic of mo in Such machines when operaiuig at :1hi her mic of spccfl than any ClllllllES with which I am fannhnr, lowit,

The driving Wheel A is normally free lo roiarc on the shaft B which isjouriizilcd at I) in an arm F and {Ill 5" in the frame of 'he machine,and said wheel has hearing on a eleeve a on id sha ft. wh -cl isillusiiralecl :i.= perforzilcwl axially.- ns at are -3, and ens forconnecting minim-{l i0 isliile in sraiz' on one eml may ha "4: them to aclnich 0;) u 7 Such means ill e3. arr. lll'tililS (a which arel'cceii'eclin :2 clutch operating member clutch pins are illuslreled asround 1 ii of ihal shape.

The clutch opvrnting member I as illuslrnled, in lhe form of :1 collarwhich is kcyeil 0!: ch! shaft B by a key (Z nnd has circumfwcmial grom'ed for receiving the howls 1* of the (llifrll pim.

If clrsired a band or collar Z1 may ho suitably secured to theshaft B for the purpose of holding the wheel A against movement thereon,and if employed a groove (2 may be cut upon the inner side of the collarD to pass over the some,

The pin operating collar D is spring impolled normnllyto its. operativeor coupling posjion by coiled springs d, which are received in axialrecesses ,a, and at ill-sir outer a plate Z1 which fixed at'the end ofthe shaft .1. 'Snitahle, means may he cmplt'iyed tomove the slidingclutch collar. such means as i lustrated comprising a r tary earn (1upon the periphery of the collar D by meam of \vl ich the said collarmay no vvitlnlrzmn from ih operative or clutching -p.,sition througheontact \vitn a inovahle trip E. This trip is pivoted a. 1.- to theframe I of the machine. A (oiled spring 1? encircles a small stud f uponthe frame l, as well as a small lag upon the arm 1" which carries thetrip and normally INK-$505 the trip to position in the path of the ram1"". where upon the rotation of the collar 1) the said trip will engai ethe beveled face of Ftlitl cam. and riding upon the top thereof willforce the cam hack, withdrm'ing the pins from operative position. A link1;" is attached to thetrip and may he connected to a suitable treadletor'the purpose of withdrawing the trip when desired. and the mualnit-am may he provided for holding this treadle dov-xn.

When the clutch pins C are thrust to the left in Fig. 1, they come inthe path of stop ahouldc or ahutments npon a collar G that is fixed tothe shaft B so as to revolve therewith. This eollar is immovable on theshaft. and may provide one of the means for holding the driving wheel Ain position.

Upon operative face itis illustrated as having wo abntutents against-\lli('ll the .{nns L1 hear. The entrance to these ahutmenta preferablyslopin; or inclined, as

For the purpose of easing the Show]; p10

(luced hy the axial thrn t when the. pins are moved to couplingposition. I regard the said inclined entrainan important in that: itinsures that the clutxh pin- \v'll engage the Said alnltmcnts men whenthe said pins are traveii 1 at the high rate of speed men tioned. andthat they will do fitilfill' and without shock. I have illustrated theemployment of two sliding" eluteh pins and correspondin? ahutments whichare oppositely disposed. and regard itits important that at hast two ofsuch pins and ahut mentsahould he ennplqved, and that they should hedisposed so that the strain shall be borne upon opposite sides of thedriving wheel. 'lherehy the halanee of said wheel is maintained anduneven wear thereof or of the hearing is prevented, and this I regard asimportant.

I have here illustrated and described a practical application of myin'iproved clutch,

but I do not. regard tne same as neeexmrily confined Within the limitsof the particular mechaninn illustrated, as various equivalents might beused for many of the elements illustrated. and the same might he iuolitiet or changed to suit p: rticular requirements, without departingfrom the essential spirit of the invention.
